So the TV's volume properties show on-screen but the volume does not increase/decrease? It is the same volume slider that your TV's remote invokes when attempting to adjust the volume? That is bizarre.
There are only two places to adjust volume properties. Your cable box menu for volume/sound properties will adjust the output type (mono/analog - digital/surround sound) and line level (linear - fixed - variable). Your television menu will have settings for output type and equalizer settings.
One thing I might suggest is to unplug your cable box for a minute or two to reset it and then try the volume adjustment again.
Refresh my memory and give me your TV make and model and your cable box make and model, too. I'll investigate a bit when I have time.
No Majestic the sliders are different in position and design. The television slider is vertical on the left margin and the remote is along the bottom.
t is a 56" HD Samsung model #HL56A650. As mentioned above we are using a Cox supplied cable converter box and it is a Motorola Model DCT2500. More specifically, I guess, a DCT2524/1631/AL (upgrade perhaps) as a number just below the DCT2500 call out on the bottom of the converter.
My son hooked the whole thing up so is it a possibility the volume plug ins are wrong in the back?
I could take a picture of the two machines in the back and email them to you if that will help.
